Solar System Flashcards
10 % of the sun’s total volume and the innermost layer of the sun.
Core
The process wherein planets are formed by collecting grains.
Accretion
Layer of a star’s interior where energy is primarily transported toward the exterior by means of radiation.
Radiative Zone
Zone with mass movement of plasma within the star which usually forms a circular current.
Convective Zone
Plasma extending into space easily seen during a total solar eclipse.
Corona
It is the region from which externally received light originates.
Photosphere
Irregular layer above the photosphere that is invisible due to the brightness of the photosphere.
Chromosphere
It is a sudden brightening observed over the Sun’s surface, which is interpreted as a large energy release.
Flare
It creates a natural boundary between the terrestrial and gaseous planets, but it could have been a planet.
Asteroid belt
An area containing rock/ice bodies beyond the orbit of Pluto.
Kuiper belt
Dark regions of the sun.
Sunspot
A cloud containing “dirty ice” well beyond the orbit of the Kuiper Belt. Comets are from this cloud.
Oort Cloud
Bright feature extending outward from the Sun’s surface, usually a loop.
Prominence
Process wherein the earth undergoes accretion and it orbits around the sun.
Great Bombardment
Moon orbits the Earth every how many days?
29 and 1 half days
How many degrees is the moon tilted?
18.5 degrees
True or False
The moon’s face does not change at all.
True
It is when the moon has only one face when facing the earth.
Tidal lock
A chuck of ice and rock originating from the outer solar system, often accompanied by coma and tail.
Comet
A rock in orbit generally between Mars and Jupiter. Sometimes gets bounced towards Earth.
Asteroid
Space rocks smaller than an asteroid.
Meteoroid
Space rock entering the atmospheres
Meteor
Space rock that lands on earth.
Meteorite
